Unlike what we usually think, the brain remains active even when it is apparently resting. The activity of the brain organ at rest, that is, without the presence of any stimulus or task, is structured and responds to certain patterns or spatiotemporal networks: the so-called resting-state networks (RSN). Neuroscientists from Pompeu Fabra University (UPF) have just deciphered the keys to its operation.
The surface of our body contains a multitude of ideal environments for the growth of various species of microorganisms that play a fundamental role in our health. Now, a team of scientists from the National Human Genome Research Institute and the National Cancer Institute (USA) has drawn up the first map of the fungi that inhabit our skin.
How to study the eating habits of a disappeared species such as the Neanderthal? Although it seems a difficult question to solve, the elements present in the fossils can give clues to solve the enigma. In a new study published in Nature, a team of scientists has studied the barium levels in the teeth of a young Neanderthal, and the results reveal that he was exclusively breastfed for seven months.
A gigantic tornado in the southern area of Oklahoma City has caused significant damage, leaving 50 people dead and many injured. The Storm Prediction Center of the National Oceanic and Atmospheric Administration (NOAA, for its acronym in English) has indicated, in its first estimates, that it was an EF4 category tornado with winds of up to 320 kilometers per hour.
About 40,000 years ago, the last Neanderthals (Homo neanderthalensis) came to live with modern man (Homo sapiens), as shown by the latest dating made in the cave of La Güelga (Asturias) by researchers from the UNED.
This is clear from a European study of Belgian, Dutch, Swedish and Irish researchers who claim that our ancestors of the Victorian era were more intelligent than us. Specifically, his work, published in the magazine Intelligence, shows that the reaction time of human beings has been lowered from 1889 until now in the West, and that this would be related to a lower IQ, which has decreased by 14 points, that is that is, 1.23 points per decade.
Scientists at the University of Arizona participating in NASA's Mars Reconnaissance Orbiter (MRO) mission have calculated that the red planet is bombarded by more than 200 small asteroids or comet fragments each year. These impacts create craters with diameters of at least 3.9 meters wide, which are being studied by experts. In total, the scientists calculate that, in a single year, the impacts affect an area the size of the state of Texas (United States).
Insects are an important and easily accessible source of nutritious and protein-rich foods found in forests, according to a new study presented by FAO at the International Conference on Forests for Food and Nutrition Security held these days in Rome. Insects are estimated to be part of the traditional diets of at least 2 billion people. In addition, the collection and breeding of insects can generate jobs and income also at the industrial level.
